j UNITED STATES PATENT EEICEC IMPRovEMEN-r IN BooT AND SHOE SOLEcHANNELlNe-MACHINES.

- Specification forming part of Letters Patent No. 146,669, darcddaruary1874; application filed January 2,1874.

To all whom it may con-cern.:

Be it known thatwe,CHAs. GOODYEAR, Jr., and GERrsTIAN DANCEL, both ofNewYork city, New York, have invented new and useful Improvements inBoot and Shoe Sole Channel ing-Machines, of which the following is aspecillication:

The machinery to which our invention is particularly directed is thatadapted to channel boot and shoe soles, to prepare them for machine orhand sewing. '4

The soles, for this purpose, have formed in` them, on one of theirfaces, an inside channel or slit extending parallel with the edge of thesole, and an outside angle L or V groove or feather or beveled edge,according to the style of shoe it is desired to make. Soles have beforebeen thus channeled by machinery.

One object of this invention is to dispense with the feeding deviceswhich have here tofore been commonly used in suclr machines. Another is,an improved method of holding the sole while it is being channeled, sothat it need not be distorted, twisted, `or stretched out of shape,lasisfrequently the casein channeling soles where theleather is thin andsoft or spongy. Another advantage is, that the sole-holder does not clogagainst ithe edge-guide, as soft soles are apt to do.

The .machine in which these improvements are embodied is characterized,chie1iyby the following features: First, an inside channel such a manneras. either .togage from the top surface of the sole, in which case theedges -of thc soles, when channeled, will vary in thickness according tovariations in the thickness of the leather; or this cutter may beattached to the frame in such manner as to reduce the edges of the solesto a uniform thickness, irrespective of variations in the thickness ofthe leather; third, the mechanism upon which the cutters are mounted ismade to traverse back and forth upon a bedplate or slide similar to ltheslide of an engine-lathe, the surface of one of its edges forming therest or support for the sole-holder hereinafter described, and takingthe place of the bottom roll or revolving table usually forming thesupport for the sole in machines of this class; fourth, a sole-holder,which consists of a plate of suitable materialpreferably brass orironhaving the form of the sole, and surrounded by a Vrim inclosing theedge of the sole, to keep the same in its place,

and to preserve it from being distorted while being channeled.`

We will now proceed to describe the manner in which our invention is ormay be carried into effect, by reference to the accompanying drawings,in whichi Figure l is a perspective View of a machine made in accordancewith our invention. Fig.

2 is a side elevation of the same, showing a sectional view of the soleand sole-holder. Fig. 3 1s a view of the sole-holder.

-The slide-rest or table is shown at A. Suit! ably supported upon it, soas to be capable of l longitudinal movement, is the head B, whichcarries the cutters. Asthe essential features of this part of themechanism have been fully described in former patents, (notably in thatissued to Benjamin H. Hadley, September`30, 1873, No.143,237,) and as itforms `no essential portion of what is claimed in this improvement, wedo not here enter into an extended description of the same, but simplyindicate the several parts, referring to the said Hadley pat` ent for aparticular description of the organif` zation and mode of operation. Cis the` arm that carries the slanting cutter. D is thevertically-movable head, to which said part- G is pivoted. These partsare raised, the arm `C iirst, and the head D afterward, by a lever,E,

pivoted to the main head B, with a shorter arm upon the sole between theoutside-groove cnt-l ter and the slantin g cutter.

The longitudinal backward and forward movement of the head B may beimparted by a screw, or in any suitable manner; but the plan which Weprefer, and which is illustrated in the drawings,is,bym.eans of a rackand pinion, the rack R being placed upon the edge of the table or slideopposite to that used as a support for the sole holder. rlhe pinion l ismade fast to one end ofthe shaft F,upon the other end of Which shaft isthe presser-roll G, with a roughened or toothed periphery, which bearsupon the edge of the sole Within the soleA holder, and travels, in astraight line, along the table A, the edge of the sole being brought inthe path of the same, and of the cutters or groovers, by themanipulation of ihe operator. The object of this presserlroll is to bearupon the sole held in the sole-holder, so as to keep both from slippingalong upon the table when the cutters incline to drag the same in theoperation of cutting the channels. This action of the presser-roll isdue, in part, to the fact that it receives apositive movement ofrevolution, which movement tends to hold the vsole and sole-holderstationary While the head B moves. Y

The sole-holder, to Which reference has been made, is indicated by theletter I. It consists, in this instance. of plate,'surmounted by a rim,flange, or Wall, of less height than the thickness of the sole, theinner face of said -flange having the contour or configuration of thesole, so that the latter Will fit snugly Within it.

The exterior edge of the holder, in the present instance, constitutes apattern, and, by keeping it pressed against guide H, the sole will,during its varied movements, be maintained in its proper position underthe cutters. The sole, instead of beingfed or drawn through between feedrolls, or other feeding device, against the action of the cutters orchannellmives, is simply placed in the holder, and laid upon the tableA, as represented in Fig. 2, and is turned and guided by the operator insuch a manner that the presser-rollshall travel at a uniform distancefrom its edge. Inl

same purpose, such as a stud or pin traveling in a groove on the underside of the sole-holder,

or in the edge of the same, in which manner the Y guiding and turning ofthe sole might be made automatic; but no claim is here made to any ofthese devices.

It is obvious that, for convenience of Working, the table or support forthe sole should be as long as the distance around the largest size ofsole, and that a separate sole-holder is required for each size.

lt is also obvious that the machine-head, iustead of traveling back andforth in a straight line, might be made to travel in a circle.Y

That We cla-im, and desire to secure by Letters Patent, is-

l. A channeling-machine in which the chan nel knives or groovers aremade to travel or move along' over the Work-'supporting table in a pathiudependent'of the pattern or outline of the sole to be channeled, thesole being relatively stationary, instead of being fed or forced againstthe channel-knives by feeding devices, substantially as shoivn'and setforth.

In a channeling-machine the combina-tion, with the supporting-table, ofthe euttercarry-v ing head sliding thereon, substantially in the mannerand for the purpose described.

3. The combination of the supporting-table and the rack thereon, withthe drivin g-pinion engaging' said rack, and mounted on a shaft carriedby the movable or sliding cutter-head, substantially as and for thepurpose described.

4. The' combination, with the sliding .head and the cutters, of thepresser-roll, carried by said head, and acting upon the sole during theY cutting or channeling operation, substantially in the manner shown andset forth.

5.' The presser-roll, carried bythe sliding cutter-head, and positivelydriven or rotated in the direction herein specified during themovementof said cutter-head, as and for the purposes stated.

(i. In machines for channeling the soles of boots and shoes,ansole-holder, hanged or recessed to receive and hold the sole duringtheV channeling operation, substantially as and for the purposesdescribed.

In testimony whereof We have hereunto signed our names this 31st day ofDecember,- A. l). 1873. i
